【摘要】：在公路橫風多發(fā)區(qū)域,因突發(fā)性及隱蔽性等特點,極易對車輛安全行駛造成威脅,常導致惡性交通事故。目前國內(nèi)對橫風多發(fā)路段汽車的行車安全限速研究相對較少,較難滿足橫風氣象下的安全需求。此外,橫風作用下,不同車輛抗風能力有很大差異,若能對大小車輛區(qū)別限速,則對交通管理以及安全信息發(fā)布都有積極的意義。文中根據(jù)道路行車安全分析理論及空氣動力學理論,充分考慮大、小型車對橫風的安全敏感閾值存在差異,分別建立不同條件下的安全限速模型,并通過Carsim/Trucksim等軟件對模型計算結(jié)果進行仿真分析,以保證所建模型能夠較為準確地反映橫風作用下的汽車動態(tài),最終能夠較好地服務(wù)于橫風行車安全預警系統(tǒng)。
[Abstract]:In highway wind-prone areas, it is easy to threaten the safety of vehicles because of the characteristics of sudden and concealment, and often lead to malignant traffic accidents. At present, there are few researches on the speed limit of cross wind multi-section vehicles in our country, so it is difficult to meet the safety requirement of cross wind weather. In addition, the anti-wind ability of different vehicles is very different under the action of crosswind. If the speed limit of large and small vehicles can be distinguished, it will be of positive significance to traffic management and safety information release. According to the theory of road safety analysis and aerodynamics, the safety sensitivity threshold of large and small vehicles to crosswind is considered in this paper, and the safety limit models under different conditions are established respectively. The simulation results of the model are analyzed by Carsim/Trucksim and other software to ensure that the model can accurately reflect the vehicle dynamics under the action of cross-wind, and finally serve the safety warning system of cross-wind vehicle better.
